The document discusses client-server network architecture where each computer or process is either a client or a server. It describes characteristics like clients initiating requests and servers waiting for and responding to requests. It also compares client-server architecture to peer-to-peer and client-queue architectures. Some advantages are well-defined roles and responsibilities and centralized data storage while disadvantages include potential traffic congestion and lower robustness compared to peer-to-peer networks.

4. Initiates requests
Waits for receives replies
Usually connects to a small
number of Servers at one time
Waits for requests from clients
Usually accepts connections from
clients
Does not intereact directly with
end users

5. Two tiered.. THE three applications
layers are mapped onto
Two computer system -the client &
the server. client can be-thin client or
fat client.
Three tier– The three applications
layers are mapped onto three logically
seprate processors that executes on
different processors.

6. Another type of network architecture peer to peer ,because each node or instance of
program can simultaneous act as both client& a server.

7. The client queue client allows end points to be simple clients, while the server consists of
some external s/w, which also acts as a passive queue database. This allows greatly
simplified s/w implementation.
